    The Pilot looks at the (External Image)Target through the HUD superimposed with the various marking in HUD. But if this were to be a holographic, I guess the Pilots attention is diverted to the details in holographic projection, and also cause obstruction to the view of the External Image.
    I guess the holographic may not suit the Fighter pilot, but may be to a Bomber, command base or on a Helicopter (not sure of the Attack one’s). ..and also to the Ground based units controlling the UAV’s.

    Wow !!, These are Excellent photographs !!! Great.
    So far I have never managed to get an Airborne Aircraft in focus, and with a 500mm lens it was hell, so I settled for Stationary ones 🙂
    Out of Topic: but could not resist, which camera and lens did you use.

    Hi Harry,

    > Most ATR enclosures will have VME/cPCI/PCI module boards.(also for
    > expansion) You have a whole range of ARINC 429 and Dual node MIL-STD-> 1553B interfaces for PCI.
    Thanks for the Info. I was under the Impression there would be no PCI slots on an Onboard Computer of the Plane.

    Hi
    In My entire experience in embedded, I have worked with C or Assembly. Documentation is not a problem due to comments and the next person to read it, knows what it is for and what the code should do.
    About C++ being Fast and close to Assembly, Well that depends on Optimization used while compiling. But C will be a sure bet any day, As C++ itself is developed using C. There is lot of wastage of Code memory and unnecessary wrappers (some times) or overriding functions that eat up memory on stack as-well-as consume time. But …If you are to design a Big Software like ATC where there are many modules, then Obviously C++ is a good language to use also I have seen it been used in Simulation softwares. But if its small thing ..Lets say drive the 1553B card, then it’ll be C ..I am not sure on ADA.
    But there could be people using C++ for small application in embedded scenario, but I personally feel that is not a good solution. May be I am wrong.

    I guess you mean to say Object Oriented Programming, Creating Objects for an entity, Well I have seen people use that in simulation , where each object in the view is an Object, and has some behavior associated with it, could be Visual or Action.

    Hi Harry !,
    > It has PCI Mezzanine card based MIL-STD-1553B

    Will there be any PCI slot on board a plane ? I am not much aware of it, but the only one I saw was for testing and simulation. Could you pls give some info on it.

    Hi seb92100!,
    > Does anyone use C++ for an embedded aeronautical software ? Java ?
    Well, C++ are used in some ATC application, but on a Missile or Fighter plane , I guess No !, I guess not even on the Washing machine, Reason are ..Speed, Code foot print and hardly use for Code reusability.
    Going in for VLSI would be better as it’ll be faster than a Code running on a Processor, efficient and more reliable.

    I think the i860 processor which is RISC, is the predecessor of i960. i860 was never popular as it was not available to general public, it was supplied to US defense only (I guess). I don’t know where i860 were used, missiles, planes or radars ?, but it was a 32bit with 64bit FPU and obviously of Mil spec.
    Any Info on what processors are used on AIM-7 type missiles ?

    US won’t risk a war with China. All US will do in case of a war, between China and Taiwan is to criticize it, and impose some sanction, that too it’ll be lifted with in a decade.

    Hi ,
    Dont know much on this and not sure but I read this somewhere, the Local telephone network and Satellite-linkup or the Mobile phone base station and satellite link gets disrupted when a Stealth aircraft flies between it (over it). This also casts a shadow over the satellite that could be used to detect the type of plane.
